Factor out the largest possible common factor.
-$$s \left( t ^ { 2 } - 7 \right) + 15 \left( t ^ { 2 } - 7 \right)$$
A) $\left( \mathrm { t } ^ { 2 } - 7 \right) ( \mathrm { s } - 15 )$
B) $15 s \left( t ^ { 2 } - 7 \right)$
C) $\left( s ^ { 2 } - 7 s \right) + \left( 15 t ^ { 2 } - 105 \right)$
D) $\left( t ^ { 2 } - 7 \right) ( s + 15 )$

Question

Quizplus · Accepted Answer

The expression $(t^2 - 7)$ is common to both terms, so it can be factored out, resulting in $(t^2 - 7)(s + 15)$.

Factor Out the Largest Possible Common Factor s(t2−7)+15(t2−7)s \left( t ^ { 2 } - 7 \right) + 15 \left( t ^ { 2 } - 7 \right)s(t2−7)+15(t2−7)

Factor Out the Largest Possible Common Factor $s \left( t ^ { 2 } - 7 \right) + 15 \left( t ^ { 2 } - 7 \right)$
